I saw the following error, when i tried to buy 15 lots of sensex hedges. I checked the websocket data and the OI was more than 1000 lots. Why did zerodha throw this error?
Error:MARKET orders are blocked for this SENSEX contract due to its open interest (OI) being less than 500 lots. You can place MARKET orders for strikes with OI above 500 lots.
